k i swapped out my ebay cold air intake that i had and put back in the stock airbox with a k&n.

while i was at it i cleaned the maf, iac, and tps. i got it all together and now it idles a lot better but when im driving 1st and 2nd gear feel fine, but 3rd and 4th feel sluggish in the lower rpms. almost like it wants to bog down.

this just started after putting back on the stock airbox.

anyone have any ideas??

At wot do you have any power lose? When my maf went bad it did something similar but I had a hug loss of power when getting on the gas. As far as normal driving it did the same thing as you describing.

Reclean the MAF if your filter was oiled at the time of installation.

I agree that the MAF might be acting up at higher RPM's/speeds/loads.

Good luck.

You may also have to do a stradegy reset. PCM uses a baro reading from MAF sensor,it isn't a real baro reading but an infered value but if your baro reading was say 145 because of a dirty MAF then PCM thinks you are below sea level. Usually doing several WOT burst will reset it but sometimes you will see a stubborn one and you have to unhook battery for about 30 min and let it reset that way.
